I understood.

I have two concerns as follows.
- I think that there is possible that progress_report() is called
frequently ( less than 1 second).
That is, progress_report() is called with force == true after
progress_report was called with force == false and execute this
function.
- progress_report() is called even if -P option is disabled. I'm
concerned about that is cause of performance degradation.
